Chlorination of geminal bis(alkoxy-NNO-azoxy) compounds with sodium hypochlorite
摘要:
Chlorination of geminal bis(alkoxy-NNO-azoxy) compounds with sodium hypochlorite involves the central carbon atom and gives 1,1-bis(alkoxy-NNO-azoxy)-1-chloroalkanes with high yield. Dichlorobis-(methoxy-NNO-azoxy)methane oxidizes sodium iodide to elemental iodine. The signal from the central carbon atom in the C-13 NMR spectra of bis(alkoxy-NNO-azoxy)dichloromethanes is broadened and displaced downfield relative to those of the initial compounds.

stable alkylationproducts of alkyl and aryl nitrosohydroxylamines seem to exist in a hitherto unknown structure, the diimide dioxide linkage. The alternative possibility is the alkyl diazotate monoxide structure, but the latter cannot account for the pure methane evolved when the substances are treated with methyl halideGrignard reagent. The principal products of this reaction with Grignard reagents

Reaction of bis(methoxy-NNO-azoxy)methane with formaldehyde in ethanol gives 3-ethoxy-2,2-bis(methoxy-NNO-azoxy)propan-1-ol as a minor product along with target 2,2-bis(methoxy-NNO-azoxy)ethanol. The structure of the former was confirmed by the counter synthesis and X-ray diffraction analysis.

Hydrolysis rate of alkoxy-NNO-azoxy compounds like di(methoxy-NNO-azoxy)methane I, di-(methyl-NON-azoxy)formal II, di(methoxy-NNO-azoxy)methane III, and 2,2-di(methoxy-NNO-azoxy)propane IV in 5 M KOH solution was measured by manometric method at 80°C; rates relation is 1:40:540:10. Reversible deprotonation to form C-anions followed by their rapid decomposition is a presumable mechanism for compounds
二(甲氧基-NNO-甲氧基)甲烷I,二-(甲基-非-甲氧基)甲醛II,二(甲氧基-NNO-甲氧基)甲烷III和2,2-二甲氧基等烷氧基-NNO-甲氧基化合物的水解速率在80℃下通过压力法测量在5M KOH溶液中的(甲氧基-NNO-氮氧基)丙烷IV;比率关系是1:40:540:10。可逆的质子化反应形成C-阴离子,然后迅速分解,这是化合物I-III的推测机制。在化合物IV的情况下,OH阴离子对CH 3 ON = N(O)基团的碳原子的亲核攻击是最可能的水解第一步。
